A Nature study from Matt Vander Heiden’s laboratory, in collaboration with MGB’s Rakesh Jain and Harvard’s George Church helps illuminate the factors determining where cancers can metastasize. In mice, the researchers quantified levels of metabolites in multiple tissues, investigating their relation to breast cancer cells’ ability to grow in different organs. They found a complex interplay of multiple nutrients in the local environment defines the sites of breast cancer metastases.This work was supported in part by The Bridge Project.
